We had a terrible smell around our caravan which we thought originally was coming from our toilet, but this proved not to be the case, so thought it may be a gas problem but this proved not to be the case! All we could think that it was a blocked drain as we were pitched near to the motorhome service point. I reported my suspicions to I think Tom who said he would look into it. Later that day as we returned to the caravan, the smell was still bad so I went and found him to see what he had discovered. He had found no problems with the site drainage but offered to come and investigate with me even though it was nearly eight o'clock at night. Within a few minutes he diagnosed it was probably our battery that was causing the problem and on checking, the battery was busy boiling away in the battery box underneath one of our berths! He advised me to immediately disconnect the power cable, which I did, and I strongly suspect that if I hadn't we would have had a fire imminently. I cannot thank him enough for his dedication to making sure we resolved the problem and preventing us from having a disaster. Btw the rest of the staff are great here too!
